Shared Virtual Server HTTP to HTTPS redirect

If you're trying to insert the output from an SSL-based command, you'd want to only attempt it for HTTPS connections. The SSL:: commands wouldn't be valid if the clientside connection was non-HTTPS. So add the header insert line within the 'else' block of the HTTP_REQUEST event:

 
 when HTTP_REQUEST { 
  
     If redirect_http_to_https is enabled and the request was made to an HTTP port, redirect the client to the same host/URI over HTTPS 
    if { ($::redirect_http_to_https == 1 or ([info exists redirect_http_to_https] && $redirect_http_to_https)) && \ 
       ([info exists vip_http_port] && $vip_http_port==1)}{ 
  
       HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri] 
       if {$::debug}{log local0. "redirecting client [IP::client_addr] to https://[getfield [HTTP::host] \":\" 1][HTTP::uri]"} 
  
    } else { 
       HTTP::header insert SSLClientCipher [SSL::cipher name],\x20version=[SSL::cipher version],\x20bits=[SSL::cipher bits] 
    ... 
    } 
 } 
 

If you're already checking that the requested port is HTTPS before trying to insert the HTTP header, can you post the full rule you get the error with?

Another way to insert a space would be to wrap the header value in double quotes:

HTTP::header insert SSLClientCipher "[SSL::cipher name], version=[SSL::cipher version], bits=[SSL::cipher bits]"
